单词	singular value decomposition
释义	singular value decomposition Mathematics For an m×n matrix M of rank r, there exists an orthogonal m×m matrix P and an orthogonal n×n matrix Q such that $P M Q = [\begin{matrix} D & 0 \\ 0 & 0 \end{matrix}],$ where D is an r×r diagonal matrix with decreasing positive entries. The pseudoinverse M⁺ of M is given by $M^{+} = Q [\begin{matrix} D^{- 1} & 0 \\ 0 & 0 \end{matrix}] P .$ Compare spectral theorem.
